The 2018 WWE Superstar Shake-up was the twelfth WWE draft, produced by the American professional wrestling promotion WWE between the Raw and SmackDown brands. Instead of a traditional draft, changes between the brands were made behind the scenes, with moving wrestlers simply appearing on a brand's show or announced via WWE's website or social medias. The two-day event took place on the April 16 and April 17 episodes of Monday Night Raw and SmackDown Live, respectively, on the USA Network in the United States. Raw was broadcast from Hartford, Connecticut at the XL Center, and SmackDown was broadcast from the Dunkin' Donuts Center in Providence, Rhode Island.

SmackDown is a brand of the American professional wrestling promotion WWE that was established on March 25, 2002. Brands are divisions of WWE's roster where wrestlers are assigned to perform on a weekly basis when a brand extension is in effect. Wrestlers assigned to SmackDown primarily appear on the brand's weekly television program, Friday Night SmackDown, also referred to simply as SmackDown. It is one of WWE's two main brands, along with Raw, collectively referred to as WWE's main roster. The brand extension was discontinued between August 2011 and July 2016.
